Have a shop hook up a live data real time scanner and read the VSS input to see if the sensor has no output.

SOURCE: I have a 2002 mazda

Can't solve, but, had the same problem. Replaced everything the codes indicated. Drove a couple of weeks and the transmission went. Third gear is gone.

Almost $ 2000.00 to chase the codes, now the transmission is going to cost $ 2,700.00 to rebuild.

Take car to a trans. shop before the transmission burns up and the rebuild will be less!!!!

SOURCE: 99 alero won't shift to third going uphill till it

Couple of things that could help is make sure your transmission fluids are at the proper level.

Also the another condition that may be caused by the molded seal portion of the direct clutch piston assembly delaminating from the steel housing eventually causing the outer lip of the piston seal to cut or tear. This cut or tear prevents the direct clutch piston assembly from applying causing the loss of both third and fourth gear.
To correct the above condition, install a Tech 2 to the vehicle and command third gear. If third gear does not exist, proceed with an inspection of the direct clutch piston assembly for the cause listed above. If the direct clutch piston has a torn seal, replace it with a new piston that has been released to prevent this condition. Inspect and replace any other parts that show potential damage or quality concerns
dak408_33.gifWith Transmissions it could be a simple to a complex repair , it also could be a
sprag assembly even.
Unfortunately to do this test you will have to seek a Transmission Professional to confirm. I am sure this is not what you wanted to hear but throwing parts at it hoping to correct the problem will only cost you more money.

Where is the speed sensor located on a 2002 oldsmobile intrigue

It is on the outside of the transmission where the speedometer cable used to go in older cars. It has a 2 wire barrel shaped about the size of a Cuban cigar.

What problems does a bad speed sensor cause

A defective speed sensor will normally cause the check engine light to illuminate as well as affect speedometer operation/cruise control operation/and transmission shifting depending on make and model. It should not affect the vehicle from reaching speed. IS the check engine light on? If so, was it scanned for codes that may point you in the right direction. You may have an exhaust/converter problem starting to develop that will cause a lack of power resulting in reaching higher speeds

Where is the speed sensor located on a 2002 Chrysler Concorde

Beware speed sensors seldom fail. Chrysler products transmission have a limp mode where they only shift to second gear when something goes wrong and many times when nothing is wrong. If the speedometer fails it goes to limp. If an OBD scan gives a transmission code sometimes clearing the code will end the problem. When driving if the transmission shifts one time as it should the sensor is working.

Engine idles up and down shifts hard transmission has been rebulit pcm gives a mass air flow troubble code replaced it problem unresloved

You need more information. I would start looking for a vacuum leak, especially if the mass air flow sensor is still not giving the desired readings. The O2 sensors will likely also be off.

2002 Alero shifting hard

I have a 1999 Oldsmobile Alero and my car was running rough and stalling. Also when the car was shifting, it was making a "thud" sound. My service engine light was on, so I took it to Autozone to run their diagnostic tool. It came back with code P0108 and they advised me to check my vacuum hoses as a possible solution. I looked and found that my air hose running from my throttle body to my map sensor was disconnected. I reconnected the hose and the engine ran normally and didn't make any "thud" sound when shifting. My car is back to normal. So check your hoses. If its still running rough, you may need to replace your map sensor.
